IOAT-HULLER.

SPECIFICATION forming part of Letters Patent No. 418,865, dated January 7,1890.

Application filed October 11, 1889. $eria1 No. 326,731. (No model.)

i To all whom it may concern.-

Be. it known that I, LOYD C. DIBERT, a citizen of the United States, residing in the city and county of San Francisco, State of California, have invented an Improveinentin Oat- Hullers; and I'hereby declare the following to be a full, clear, and exact description of the same.

My invention relates to the classof grind ing-mill-stock machinery, and especially to oat-hullers; and myinven tion consists in the details of construction, arrangement, and combination of devices hereinafter fully described, and specifically pointed out in the claims.

The object of my invention is toprovide a machine of this class of great capacity and adapted for rapid and effective work.

Referring to the accompanying drawings fora more complete explanation of my invention, Figure 1 is a side elevation of my oat-huller. Fig. -2 is a horizontal section through the frame-work to show the adj usting mechanism in plan.

A are four fixed posts,which form the framework for supporting the general machine.

B represents, generally,the hullers'arranged independently of each other and in vertical bottom of the case, and over which the runner operates.

separate hullers, and the runner of each is Ihave here shown three of these keyed to the central spindle E, which drives them all. This spindle has its lower end stepped in a vertically-adjustable box e, with the top of which the pivoted lever e engages, said lever being connected at one end with a screw 6 which passes up through the fioor X and receives a hand-nut 6 upon its upper end, by the movement of which the central spindle is raised or lowered, in order to simultaneously adjust all the runners. This mechanism is the ordinary means for adjusting the runner of a single huller.

The bed-stones are supported and are indepen dently and separately adjusted, as follows: Extending from the base of each bedstone, at its four quarters and opposite the four postsA, are the lugs or'ears-d, in which are seated the leveling-screws d. Secured to and extending inwardly from the posts A are the brackets a, and in these are seated the supporting-screws a, the .upper ends of which are fitted into sockets in the heads of the screws (1'. The bed-stones are thus supported upon the two sets of screws, the screws d being for the purpose of leveling the bedstones, while the screws a are for the purpose of vertically adjusting said bed-stones.

The screws a of each bed-stone are operated by means of an endless chain F, which passes around the four of them, each screw being provided with a sprocket-wheel f, to receive the chain, and one of the screws having on its lower end a beveled gear f, with which meshes a beveled gear g on the end of a shaft G, the outer end of which carries a hand-wheel g. These shafts are journaled in and supported by brackets or hangers 9 extending downwardly from the bed-stones.

Now, by turning the hand-wheel of any shaft central spindle, it becomes necessary, in order to properly grade the work of each huller, to separately and independently adjust the bed stone of each huller.

The series of hullers communicate through a'chute H, with which the bases of the hullers communicate by spouts h, and which communicates itself with the several feed-chutes I of the hullers.

I am aware that in the ordinary single hulling-machine the runner has been vertically adjusted by means similar to the devices I have herein shown for adjusting the series of runners of my machine; and I am also aware that in said single huller the bed-stone is supported upon screws, bythe movement of which it isleveled. Ido not therefore claim merely the leveling or adjusting of the bed-stones and runners; but

Vhat I do claim as new, and desire to secure by Letters Patent, is

1. In an oat-huller, the combination of the runner, the bedstone, and the mechanism for adjusting and leveling the bed-stone, consisting of the screw (1, seated in lugs or ears on the bed-stone, the fixed brackets a, the sup porting-screws seated in the brackets and fitted into the heads of the leveling-screws, the sprocket-wheels on said supportin -screws, the endless chain engaging said wheels, the shaft supported by the bed-stone, and gearing connecting said shaft with one of the supporting-screws, substantially as herein described.

2. In an oat-huller, the combination of the vertical series of runners, the central spindle by which they are carried and operated, and mechanism for vertically moving the spindle,

whereby all the runners of the series are adj usted simultaneously, the series of bedstones, one for each runner, said stones having the lugs or cars l, the leveling-screws d, seated in said lugs or ears, the fixed brackets a, the supporting-screws a, seated therein and fitted into the heads of the levelingscrews, the sprocket-Wheels on the supporting-screws, the series of endless chains passing about said wheels, the separate shafts carried by the bed-stones, and gearing connecting a shaft with one of the screws of each set, whereby each bed-stone may be separately and independently adjusted, substantially as herein described.

In witness whereof I have hereunto set my hand.
